About Alternate Year Dimensions

An alternate year dimension may be used for a historical plan type which contains years prior to the start of the current Year dimension. This approach enables the addition of past historical years if the current Planning application's Year dimension does not include enough past years to meet prediction requirements. For example, if the current Year dimension covers FY08 to FY14, it may be necessary to add historical data from FY03 to FY07 for predictions. In this case, a historical plan type may be used with an alternate year dimension that contains members FY03 to FY07. The dimension name may be any valid custom dimension name, such as AltYear. For dimension requirements, see Alternate Year Dimension Requirements.
